谷歌应用程序引擎&x2B；python:上载到blobstore会导致编码错误

python google-app-engine

谷歌应用程序引擎&x2B；python:上载到blobstore会导致编码错误,python,google-app-engine,blobstore,Python,Google App Engine,Blobstore,我尝试使用以下HTML表单将Blob上传到Google App Engine的blobstore： <!DOCTYPE html> <html> <head> <meta charset=utf-8> </head> <body> <form id=upload action={{upload_url}} method=post enctype=multipart/form-data> Name: <i

我尝试使用以下HTML表单将Blob上传到Google App Engine的blobstore：

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
</head>
<body>
<form id=upload action={{upload_url}} method=post enctype=multipart/form-data>
  Name: <input type=text name=name>
  Your photo: <input type=file name=image required=required><br><br>
  <input type=submit value=submit>
</form>
</body>
</html>

通常，

名称

字段将填充非英语字符（例如，中文）。以上程序在我的本地SDK上运行良好。但是，当程序在Google App Engine上运行时，

名称

的编码不正确。那么问题出在哪里呢？

您不需要在meta标记参数周围加引号：

？另外，请尝试：

。另外，请确保以UTF-8编码保存模板的文本文档。

刚刚发现这是多年来的老错误，请参阅。有两种解决方案：

（1）将以下语句添加到app.yaml中：

libraries:
- name: webob
  version: "1.2.3"

（2）添加包含以下内容的文件appengine_config.yaml：

# -*- coding: utf-8 -*-
from webob import multidict

def from_fieldstorage(cls, fs):
    """Create a dict from a cgi.FieldStorage instance.
    See this for more details:

    """
    import base64
    import quopri

    obj = cls()
    if fs.list:
        # fs.list can be None when there's nothing to parse
        for field in fs.list:
            if field.filename:
                obj.add(field.name, field)
            else:
                # first, set a common charset to utf-8.
                common_charset = 'utf-8'
                # second, check Content-Transfer-Encoding and decode
                # the value appropriately
                field_value = field.value
                transfer_encoding = field.headers.get('Content-Transfer-Encoding', None)
                if transfer_encoding == 'base64':
                    field_value = base64.b64decode(field_value)
                if transfer_encoding == 'quoted-printable':
                    field_value = quopri.decodestring(field_value)
                if field.type_options.has_key('charset') and field.type_options['charset'] != common_charset:
                    # decode with a charset specified in each
                    # multipart, and then encode it again with a

                    field_value = field_value.decode(field.type_options['charset']).encode(common_charset)
                    # TODO: Should we take care of field.name here?
                    obj.add(field.name, field_value)
    return obj

multidict.MultiDict.from_fieldstorage = classmethod(from_fieldstorage)

try:test.name=self.request.get（'name'）。decode（'utf-8'）错误消息：

UnicodeEncodeError:'ascii'编解码器无法对位置0:ordinal not in range（128）

中的字符u'\u6211'进行编码。您可以尝试在不使用上载url和重定向的情况下进行上载，以查找编码问题。请看一下gcs_upload.py中的要点：谢谢。但HTML5允许不使用引用语。因此，为了提高效率，我认为最好减小HTML文件的大小。
